Without seeing the guns in hand a real accurate value is impossible to guess. No offense, one persons shiney new car is anothers worn out beater. You would be best off to have them apraised by a dealer or collector who has no interest in buying them at his estimated value. Real conflict of interest sometimes.
Should you not do that you have to educate yourself by looking at simular guns on the net. I will give you several suggestions where to look. Look at all the pictures you can to compare with your guns. Another option is to get a copy of BlueBook and try to find them in there.

Best guess, from the information you have given, is $3,124.56 but that may be plus or minus $1,000.00. Next poster might tell you your collection is worth $1.234.04. Unless you want to give the guns away or get just a fraction of their value you need to have them looked at in person. All the rest are just guesses. Be assured that the buyer will know their true value almost every time and as seller you need to also.
